Summary

Within 180 days after August 8, 2005, the Secretary must begin a partnership with diesel engine, fuel system, vehicle makers, and fuel suppliers to add biodiesel testing to advanced diesel engine and fuel system work. The testing must look at how biodiesel affects emissions rules and warranties, long-term engine performance, ways to optimize emissions and performance when switching between biodiesel and diesel, and how biodiesel performs when blended with the 2006 EPA‑mandated diesel fuel with a maximum of 15‑parts‑per‑million sulfur. The Secretary must give Congress an interim report on findings and recommendations within 2 years after August 8, 2005. Congress may appropriate $5,000,000 for each of fiscal years 2006 through 2010 to run the program. Biodiesel — a diesel fuel substitute made from nonpetroleum renewable resources that meets EPA fuel registration under section 7545 and the American Society for Testing and Materials D6751–02a Standard Specification for Biodiesel Fuel (B100) Blend Stock for Distillate Fuels.

(a)Not later that 11 So in original. Probably should be “than”. 180 days after August 8, 2005, the Secretary shall initiate a partnership with diesel engine, diesel fuel injection system, and diesel vehicle manufacturers and diesel and biodiesel fuel providers, to include biodiesel testing in advanced diesel engine and fuel system technology.
(b)The program shall provide for testing to determine the impact of biodiesel from different sources on current and future emission control technologies, with emphasis on—
(1)the impact of biodiesel on emissions warranty, in-use liability, and antitampering provisions;
(2)the impact of long-term use of biodiesel on engine operations;
(3)the options for optimizing these technologies for both emissions and performance when switching between biodiesel and diesel fuel; and
(4)the impact of using biodiesel in these fueling systems and engines when used as a blend with 2006 Environmental Protection Agency-mandated diesel fuel containing a maximum of 15-parts-per-million sulfur content.
(c)Not later than 2 years after August 8, 2005, the Secretary shall provide an interim report to Congress on the findings of the program, including a comprehensive analysis of impacts from biodiesel on engine operation for both existing and expected future diesel technologies, and recommendations for ensuring optimal emissions reductions and engine performance with biodiesel.
(d)There are authorized to be appropriated $5,000,000 for each of fiscal years 2006 through 2010 to carry out this section.
(e)For purposes of this section, the term “biodiesel” means a diesel fuel substitute produced from nonpetroleum renewable resources that meets the registration requirements for fuels and fuel additives established by the Environmental Protection Agency under section 7545 of this title and that meets the American Society for Testing and Materials D6751–02a Standard Specification for Biodiesel Fuel (B100) Blend Stock for Distillate Fuels.
